Description
ASME Section IV provides requirements for design, fabrication, installation and inspection of steam heating, hot water heating, hot water supply boilers, and potable water heaters intended for low pressure service that are directly fired by oil, gas, electricity, coal or other solid or liquid fuels.
It contains appendices which cover approval of new material, methods of checking safety valve and safety relief valve capacity, examples of methods of checking safety valve and safety relief valve capacity, examples of methods of calculation and computation, definitions relating to boiler design and welding, and quality control systems. Rules pertaining to use of the H, HV, and HLW ASME Product Certification Marks are also included.
What are the key changes for ASME BPVC Section IV 2023?
- HG-715, HG-803, HLW-810, HLW-902, HLW-903, HLW-904, & HLW-906 were revised to support the proposed drain valve language in HG-803.2(c)(3) and HG-803.3(c)(2), in order to align with the requirements in Code Cases 2873 and 2983, so they can be incorporated into the ASME Section IV code.
- ASME Section IV, Table 2-100, now references the “latest edition” of the ASME CA-1 Standard for Conformity Assessment Requirements, since Section 5.4, in the 2020 Edition of CA-1, incorporated requirements for reapplication of the ASME Single Certification Mark.
- A provision was added to HLW-602 and HG-531 for the removal of a nameplate or marking of a “Part” when incorporating the Part into a boiler that is to be certified.
